Abstract: Systems, methods and apparatus for radial amplitude assisted transfer (RAAT) in mass spectrometers are provided in which ions for RAAT are accelerated along a longitudinal axis of a mass spectrometer in order to decrease the magnitude of excitation energy of radially excited ions in an ion trap that allows the radially excited ions to exit the ion trap. Hence, the radially excited ions exit the ion trap with reduced radial energy thereby decreasing the exit angle of the radially exited ions from the ion trap. Furthermore, combined forces on the ions are such that radially excited ions exit the ion trap while unexcited ions remain in the ion trap.

Abstract: Improved packet scheduling methods and apparatuses for use in, among other things, a network interface of a router (or other network element) are described herein. In one such improved method, packets buffered in a network interface are segmented for transmission on a communications link into multiple scheduling domains each being represented by a scheduling tree, each scheduling tree is assigned to a separate virtual port scheduling engine, and a top level scheduling engine is employed to schedule between the outputs of the virtual port scheduling engines to make the final choice of which buffered packet to transmit on the communications link (e.g., to move to the transmit queue of the network interface). By having the virtual port scheduling engines operate in parallel and substantially independently of each other, the rate at which packet can be moved into the transmit queue may increase greatly, thereby increasing the bandwidth of the network interface of the router.

Abstract: Provided is a preprogrammed key fob system that allows a user to limit a vehicle top speed while the given key fob is being used to operate the vehicle. The system comprises a vehicle system and a navigation system, wherein the navigation system is disposed within the key fobs and the key fob is adapted to communicate with the vehicle system while in use. The navigation system of each key is utilized to capture the local speed limit of a given road, while a vehicle speed is programmed into the specific key to set a vehicle speed buffer above the local speed limit being traveled. The system therefore limits the user of a given key to a preset limit, which adapts in real- time based on the local speed limits and allows the owner of the keys to set the limits and to monitor the vehicle conditions using the system.

Abstract: The rate of release of encapsulated active compound from a multivesicular liposomal (MVL) formulation is modified by selection of a neutral lipid component. A family of MVL formulations containing different slow:fast release neutral lipid molar ratios displays different release rates depending upon the molar ratio of the fast release neutral lipid to the slow release neutral lipid in each member. Incubation in plasma or a plasma-like medium at in vivo temperatures so as to obtain a release rate curve for each allows selection from among the members of the family of a liposomal formulation with a desired rate of release in vivo.
